Plant water relation and regulation is important for sustainable use of soil water resources and Agriculture high-quality development in most of water-limited Regions because Soil water resources can only be used by plants and then converted into plant products and services for people to use. As population increases and economy develops in water-limited regions, there is an increasing demand for the quantity and variety of plant products and services. To meet the demands of this situation, most of the original forest has become farmland, plantation or non-native forest, grass land and farmland. As plant grow, the plant water relationship changed from equilibrium relation to non-equilibrium relationship, which led to severe soil and water loss, led to soil drought, soil and vegetation degradation, crop failure in dry years or waste of soil water in rainy years in most of water-limited regions. In order to solve these questions and improve environment and realize the sustainable utilization of soil water resources and the high-quality sustainable development of social economy, it is necessary to apply the limit theory of plant utilization of soil water resources by plants, the vegetation carrying capacity theory and critical period of plant resources relationship regulation to adjust the plant water relationship to obtain the maximum yield and benefit of vegetation and carry out Sustainable use of soil water resources and agriculture high-quality sustainable development.
